Answer to Question 1

ANS: D
Decreased levels of acetylcholine are thought to produce many of the behavioral symptoms of Alzheimer's disease. The inhibiting action the drug has on cholinesterase will slow down the breakdown of acetylcholine and so delay the onset of symptoms. The other neurotrans-mitters (GABA, dopamine, and serotonin) are not currently believed to play a role in Alz-heimer's disease.

Answer to Question 2

ANS: B
The cerebral hemispheres are responsible for functions such as control of muscles. The right hemisphere mainly controls the motor and sensory functions on the left side of the body. Damage to the right side would result in impaired function on the left side of the body. The motor cortex controls voluntary motor activity. Broca's area controls motor speech. Cognitive functions are attributed to the association cortex. The right side of the body's motor activity is controlled by the left cerebral cortex.
